Abstract

An apparatus and a method of use for removing specified dialyzable components from a complex reference fluid such as, for example, blood. The invention includes a semi-permeable tubular dialysis membrane (12), which is inserted into the reference fluid. An equilibration fluid is injected into the tubular membrane and allowed to equilibrate with the outside reference fluid. The equilibrated fluid is then removed for analysis, or possibly analyzed in situ.
